This enables the support for boot image header version 3 and 4 using abootimg command.
In order to use version 3 or 4:
1- Vendor boot image address should be given to abootimg cmd.
abootimg addr $1 $vendor_boot_load_addr
2- "ramdisk_addr_r" env variable (ramdisk address) should be set to host the ramdisk : generic ramdisk + vendor ramdisk
"struct andr_boot_img_hdr_v0*" is replaced by "void *" in some functions since v3 and v4 are now supported as well.
